Hello dear community,
I want to display the text of a figure in different colors. The text consists of several strings which are displayed with the font color black. Dynamically strings should be added to the text line by line with a fixed color if a boolean variable is true. Unfortunately I have no idea how this could work.
Here is an example how I have tried:
set(mainHandles.text, 'String', [{'abc'};...
{'dfg'};...
{'hij'};...
{'klm'};...
{'stu'};...
{'vwxyz'}]); %black font coulor
text_data = arrayfun(@(x) text(join(['\\color{x}sadfsdgs')),...
cell2mat(Data(is_true,1)), 'UniformOutput', false);
mainHandles.text.String = vertcat(mainHandles.text.String, text_modules);
mainHandles.text is the text object of the figure. Data contains the color of the respective string. With is_true the active strings are addressed.
Regardless of the fact that I have to reset the text of the figure with set, passing the font color in the string itself does not work - invalid parameter/value pair arguments.
Do any of you have an idea how I could make it all happen?
Many thanks for the help

Well, it'll take a fair amount of detailed coding, but it can be done...as a crude illustration try the following code...
close,hAx=gca;
hTxt=text(0.5,0.5, [{'\color{black}abc'};...
{'\color{red}dfg'};...
{'\color{black}hij'};...
{'\color{black}klm'};...
{'\color{black}stu'};...
{'\color{darkGreen}vwxyz'}]);
pause 5
hTxt.String(1)=strrep(hTxt.String(1),'black','red');

Nice thanks, it worked. I used RGB Triplet, so i had to replace \color{} with \color[rgb]{specifier}.
